Claims. 1

This invention relates to the construction of building walls with formsof the progressive type wherein a form positioned on a wall is removedand installed in a superimposed position as concrete sets to form aportion of a wall, and in particular this invention relates to pairs oiforms with one pair positioned upon a lower pair with the sides of thepairs tied together by Wires eX- tended therethrough, and in whichsimulated mortar joints may oe formed in the face of a wall byprojections on the inner surfaces of the outer sections oT" the forms.

The purpose of this invention is to provide a progressive type of formfor the construction of building walls wherein forms used to cast thelower part of a wall are removed and reused to cast upper parts thereof,and wherein the lower edges of the removed forms which are repositionedto form upper parts of the wall are adjustable to eliminate lines oroffsets where adjoining edges of the forms meet.

In the usual type of progressive form for concrete walls in buildingconstruction the entire form is moved upwardly and repositioned on theupper edge or" the set concrete and where forms of this type are used itis difficult to line up the inner surfaces to provide smooth anduninterrupted Wall surfaces. With this thought in mind this inventioncontemplates an improved type of progressive form wherein one sectionremains in i l,

position on a wall while a lower set is removed and installed above theset remaining on the wall and with this type of construction it ispossible to provide adjusting means between the upper edge of the formremaining on the wall and the superimposed form whereby the innersurfaces may be adjusted until the meeting edges are in common planes.

The object of this invention, is therefore, to provide means forconstructing a building wall form of the progressive type whereby lowersections are removable and installed upon upper sections and the innerfaces of the upper sections are adjustable in relation to the innerfaces of the lower sections.

Another object of the invention is to provide a building wall form ofthe progressive type in which simulated mortar joints may be provided inthe outer face of a wall formed thereby.

A further object of the invention is to provide a building wall form ofthe progressive type in which means is provided for keeping thethickness of the wall constant.

A further object oi the invention is to provide progressive buildingwall forms having upper and lower pairs of sections and in which onesection is superimposed upon another with the former section in positionon a wall, which provides a form of a simple and economicalconstruction.
